Dynamic configuration of operation power parameters

ABSTRACT

Some techniques and apparatuses described herein permit a user equipment (UE) to transition among different power configurations, which include different values for different power parameters, that impact an amount of power consumed by the UE. In some aspects, these transitions may be signaled by a base station based at least in part on traffic volume for the UE, which may assist with improving throughput and/or extending battery life of the UE. Furthermore, these transitions may be signaled dynamically, such as in downlink control information (DCI) and/or a medium access control (MAC) control element (CE) MAC-CE, which may conserve battery power and/or network resources as compared to reconfiguring the UE using an RRC message, and which may allow the UE to be reconfigured quickly as conditions associated with the UE change.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No.16/725,254, filed Dec. 23, 2019, entitled “DYNAMIC CONFIGURATION OFOPERATION POWER PARAMETERS,” which claims priority to U.S. ProvisionalPatent Application No. 62/789,304, filed on Jan. 7, 2019, entitled“DYNAMIC CONFIGURATION OF POWER PARAMETER VALUES,” which are herebyexpressly incorporated by reference herein.

BACKGROUND Field

Aspects of the present disclosure generally relate to wirelesscommunication, and more particularly to techniques and apparatuses fordynamic configuration of power parameter values.

Background

Wireless communication systems are widely deployed to provide varioustelecommunication services such as telephony, video, data, messaging,and broadcasts. Typical wireless communication systems may employmultiple-access technologies capable of supporting communication withmultiple users by sharing available system resources (e.g., bandwidth,transmit power, and/or the like). Examples of such multiple-accesstechnologies include code division multiple access (CDMA) systems, timedivision multiple access (TDMA) systems, frequency-division multipleaccess (FDMA) systems, orthogonal frequency-division multiple access(OFDMA) systems, single-carrier frequency-division multiple access(SC-FDMA) systems, time division synchronous code division multipleaccess (TD-SCDMA) systems, and Long Term Evolution (LTE).LTE/LTE-Advanced is a set of enhancements to the Universal MobileTelecommunications System (UMTS) mobile standard promulgated by theThird Generation Partnership Project (3GPP).

A wireless communication network may include a number of base stations(BSs) that can support communication for a number of user equipment(UEs). A UE may communicate with a BS via the downlink and uplink. Thedownlink (or forward link) refers to the communication link from the BSto the UE, and the uplink (or reverse link) refers to the communicationlink from the UE to the BS. As will be described in more detail herein,a BS may be referred to as a Node B, a gNB, an access point (AP), aradio head, a transmit receive point (TRP), a 5G BS, a 5G Node B, and/orthe like.

The above multiple access technologies have been adopted in varioustelecommunication standards to provide a common protocol that enablesdifferent wireless communication devices to communicate on a municipal,national, regional, and even global level. 5G, which may also bereferred to as New Radio (NR), is a set of enhancements to the LTEmobile standard promulgated by the Third Generation Partnership Project(3GPP). 5G is designed to better support mobile broadband Internetaccess by improving spectral efficiency, lowering costs, improvingservices, making use of new spectrum, and better integrating with otheropen standards using OFDM with a cyclic prefix (CP) (CP-OFDM) on thedownlink (DL), using CP-OFDM and/or SC-FDM (e.g., also known as discreteFourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), as wellas supporting beamforming, multiple-input multiple-output (MIMO) antennatechnology, and carrier aggregation. However, as the demand for mobilebroadband access continues to increase, there exists a need for furtherimprovements in LTE and 5G technologies. Preferably, these improvementsshould be applicable to other multiple access technologies and thetelecommunication standards that employ these technologies.

SUMMARY

Battery life is an important consideration for UEs, especially for UEsfor which battery replacement may be difficult, like a narrowbandInternet of Things (NB-IoT) UE that operates in a remote geographicarea. However, throughput is also an important consideration for UEs,and often directly conflicts with power savings and battery life sincemore power is required for high throughput as compared to lowthroughput. In some cases, a UE may use a discontinuous reception (DRX)cycle to transition between a sleep state and an active state toconserve battery power when there is no data for the UE to transmit orreceive. However, a UE may benefit from additional power saving inaddition to a DRX cycle or as an alternative to a DRX cycle.

Some techniques and apparatuses described herein permit a UE totransition among different power configurations, which are defined bydifferent values for different operation power parameters (e.g.,transmission power parameters or reception power parameters), thatimpact the amount of power consumed by the UE (e.g., to communicate witha base station or to perform other operations). In some aspects, thesetransitions may be signaled by a base station based at least in part ontraffic volume for the UE, which may assist with improving throughput(e.g., when data is available for the UE), and which may assist withextending battery life of the UE (e.g., when data is not available forthe UE). Furthermore, these transitions may be signaled dynamically,such as in downlink control information (DCI) and/or a media accesscontrol (MAC) control element (CE) (MAC-CE), which may conserve batterypower as compared to reconfiguring the UE using a radio resource control(RRC) message, and which may allow the UE to be reconfigured quickly asconditions associated with the UE change.

It should be noted that while aspects may be described herein usingterminology commonly associated with 3G and/or 4G wireless technologies,aspects of the present disclosure can be applied in othergeneration-based communication systems, such as 5G and later, including5G technologies.

FIG. 1 is a diagram illustrating a wireless network 100 in which aspectsof the present disclosure may be practiced. The wireless network 100 maybe an LTE network or some other wireless network, such as a 5G network.Wireless network 100 may include a number of BSs 110 (shown as BS 110 a,BS 110 b, BS 110 c, and BS 110 d) and other network entities. A BS is anentity that communicates with user equipment (UEs) and may also bereferred to as a base station, a 5G BS, a Node B, a gNB, a 5G NB, anaccess point, a transmit receive point (TRP), and/or the like. Each BSmay provide communication coverage for a particular geographic area. In3GPP, the term “cell” can refer to a coverage area of a BS and/or a BSsubsystem serving this coverage area, depending on the context in whichthe term is used.

ABS may provide communication coverage for a macro cell, a pico cell, afemto cell, and/or another type of cell. A macro cell may cover arelatively large geographic area (e.g., several kilometers in radius)and may allow unrestricted access by UEs with service subscription. Apico cell may cover a relatively small geographic area and may allowunrestricted access by UEs with service subscription. A femto cell maycover a relatively small geographic area (e.g., a home) and may allowrestricted access by UEs having association with the femto cell (e.g.,UEs in a closed subscriber group (CSG)). A BS for a macro cell may bereferred to as a macro BS. A BS for a pico cell may be referred to as apico BS. A BS for a femto cell may be referred to as a femto BS or ahome BS. In the example shown in FIG. 1, a BS 110 a may be a macro BSfor a macro cell 102 a, a BS 110 b may be a pico BS for a pico cell 102b, and a BS 110 c may be a femto BS for a femto cell 102 c. A BS maysupport one or multiple (e.g., three) cells. The terms “eNB”, “basestation”, “5G BS”, “gNB”, “TRP”, “AP”, “node B”, “5G NB”, and “cell” maybe used interchangeably herein.

In some examples, a cell may not necessarily be stationary, and thegeographic area of the cell may move according to the location of amobile BS. In some examples, the BSs may be interconnected to oneanother and/or to one or more other BSs or network nodes (not shown) inthe access network 100 through various types of backhaul interfaces suchas a direct physical connection, a virtual network, and/or the likeusing any suitable transport network.

Wireless network 100 may also include relay stations. A relay station isan entity that can receive a transmission of data from an upstreamstation (e.g., a BS or a UE) and send a transmission of the data to adownstream station (e.g., a UE or a BS). A relay station may also be aUE that can relay transmissions for other UEs. In the example shown inFIG. 1, a relay station 110 d may communicate with macro BS 110 a and aUE 120 d in order to facilitate communication between BS 110 a and UE120 d. A relay station may also be referred to as a relay BS, a relaybase station, a relay, and/or the like.

Wireless network 100 may be a heterogeneous network that includes BSs ofdifferent types, e.g., macro BSs, pico BSs, femto BSs, relay BSs, and/orthe like. These different types of BSs may have different transmit powerlevels, different coverage areas, and different impacts on interferencein wireless network 100. For example, macro BSs may have a high transmitpower level (e.g., 5 to 40 Watts) whereas pico BSs, femto BSs, and relayBSs may have lower transmit power levels (e.g., 0.1 to 2 Watts).

A network controller 130 may couple to a set of BSs and may providecoordination and control for these BSs. Network controller 130 maycommunicate with the BSs via a backhaul. The BSs may also communicatewith one another, e.g., directly or indirectly via a wireless orwireline backhaul.

UEs 120 (e.g., 120 a, 120 b, 120 c) may be dispersed throughout wirelessnetwork 100, and each UE may be stationary or mobile. A UE may also bereferred to as an access terminal, a terminal, a mobile station, asubscriber unit, a station, etc. A UE may be a cellular phone (e.g., asmart phone), a personal digital assistant (PDA), a wireless modem, awireless communication device, a handheld device, a laptop computer, acordless phone, a wireless local loop (WLL) station, a tablet, a camera,a gaming device, a netbook, a smartbook, an ultrabook, a medical deviceor equipment, biometric sensors/devices, wearable devices (smartwatches, smart clothing, smart glasses, smart wrist bands, smart jewelry(e.g., smart ring, smart bracelet)), an entertainment device (e.g., amusic or video device, or a satellite radio), a vehicular component orsensor, smart meters/sensors, industrial manufacturing equipment, aglobal positioning system device, or any other suitable device that isconfigured to communicate via a wireless or wired medium.

Some UEs may be considered machine-type communication (MTC) or evolvedor enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEsinclude, for example, robots, drones, remote devices, sensors, meters,monitors, location tags, etc., that may communicate with a base station,another device (e.g., remote device), or some other entity. A wirelessnode may provide, for example, connectivity for or to a network (e.g., awide area network such as Internet or a cellular network) via a wired orwireless communication link. Some UEs may be consideredInternet-of-Things (IoT) devices, and/or may be implemented as NB-IoT(narrowband internet of things) devices. Some UEs may be considered aCustomer Premises Equipment (CPE). UE 120 may be included inside ahousing that houses components of UE 120, such as processor components,memory components, and/or the like.

In general, any number of wireless networks may be deployed in a givengeographic area. Each wireless network may support a particular RAT andmay operate on one or more frequencies. A RAT may also be referred to asa radio technology, an air interface, and/or the like. A frequency mayalso be referred to as a carrier, a frequency channel, and/or the like.Each frequency may support a single RAT in a given geographic area inorder to avoid interference between wireless networks of different RATs.In some cases, 5G RAT networks may be deployed.

In some examples, access to the air interface may be scheduled, whereina scheduling entity (e.g., a base station) allocates resources forcommunication among some or all devices and equipment within thescheduling entity's service area or cell. Within the present disclosure,as discussed further below, the scheduling entity may be responsible forscheduling, assigning, reconfiguring, and releasing resources for one ormore subordinate entities. That is, for scheduled communication,subordinate entities utilize resources allocated by the schedulingentity.

Base stations are not the only entities that may function as ascheduling entity. That is, in some examples, a UE may function as ascheduling entity, scheduling resources for one or more subordinateentities (e.g., one or more other UEs). In this example, the UE isfunctioning as a scheduling entity, and other UEs utilize resourcesscheduled by the UE for wireless communication. A UE may function as ascheduling entity in a peer-to-peer (P2P) network, and/or in a meshnetwork. In a mesh network example, UEs may optionally communicatedirectly with one another in addition to communicating with thescheduling entity.

Thus, in a wireless communication network with a scheduled access totime-frequency resources and having a cellular configuration, a P2Pconfiguration, and a mesh configuration, a scheduling entity and one ormore subordinate entities may communicate utilizing the scheduledresources.

As indicated above, FIG. 1 is provided merely as an example. Otherexamples may differ from what is described with regard to FIG. 1.

FIG. 2 shows a block diagram 200 of a design of base station 110 and UE120, which may be one of the base stations and one of the UEs in FIG. 1.Base station 110 may be equipped with T antennas 234 a through 234 t,and UE 120 may be equipped with R antennas 252 a through 252 r, where ingeneral T≥1 and R≥1.

At base station 110, a transmit processor 220 may receive data from adata source 212 for one or more UEs, select one or more modulation andcoding schemes (MCS) for each UE based at least in part on channelquality indicators (CQIs) received from the UE, process (e.g., encodeand modulate) the data for each UE based at least in part on the MCS(s)selected for the UE, and provide data symbols for all UEs. Transmitprocessor 220 may also process system information (e.g., for semi-staticresource partitioning information (SRPI), and/or the like) and controlinformation (e.g., CQI requests, grants, upper layer signaling, and/orthe like) and provide overhead symbols and control symbols. Transmitprocessor 220 may also generate reference symbols for reference signals(e.g., the CRS) and synchronization signals (e.g., the primarysynchronization signal (PSS) and secondary synchronization signal(SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor230 may perform spatial processing (e.g., precoding) on the datasymbols, the control symbols, the overhead symbols, and/or the referencesymbols, if applicable, and may provide T output symbol streams to Tmodulators (MODs) 232 a through 232 t. Each modulator 232 may process arespective output symbol stream (e.g., for OFDM and/or the like) toobtain an output sample stream. Each modulator 232 may further process(e.g., convert to analog, amplify, filter, and upconvert) the outputsample stream to obtain a downlink signal. T downlink signals frommodulators 232 a through 232 t may be transmitted via T antennas 234 athrough 234 t, respectively. According to various aspects described inmore detail below, the synchronization signals can be generated withlocation encoding to convey additional information.

At UE 120, antennas 252 a through 252 r may receive the downlink signalsfrom base station 110 and/or other base stations and may providereceived signals to demodulators (DEMODs) 254 a through 254 r,respectively. Each demodulator 254 may condition (e.g., filter, amplify,downconvert, and digitize) a received signal to obtain input samples.Each demodulator 254 may further process the input samples (e.g., forOFDM and/or the like) to obtain received symbols. A MIMO detector 256may obtain received symbols from all R demodulators 254 a through 254 r,perform MIMO detection on the received symbols if applicable, andprovide detected symbols. A receive (RX) processor 258 may process(e.g., demodulate and decode) the detected symbols, provide decoded datafor UE 120 to a data sink 260, and provide decoded control informationand system information to a controller/processor 280. A channelprocessor may determine RSRP, RSSI, RSRQ, CQI, and/or the like.

On the uplink, at UE 120, a transmit processor 264 may receive andprocess data from a data source 262 and control information (e.g., forreports comprising RSRP, RSSI, RSRQ, CQI, and/or the like) fromcontroller/processor 280. Transmit processor 264 may also generatereference symbols for one or more reference signals. The symbols fromtransmit processor 264 may be precoded by a TX MIMO processor 266 ifapplicable, further processed by modulators 254 a through 254 r (e.g.,for DFT-s-OFDM, CP-OFDM, and/or the like), and transmitted to basestation 110. At base station 110, the uplink signals from UE 120 andother UEs may be received by antennas 234, processed by demodulators232, detected by a MIMO detector 236 if applicable, and furtherprocessed by a receive processor 238 to obtain decoded data and controlinformation sent by UE 120. Receive processor 238 may provide thedecoded data to a data sink 239 and the decoded control information tocontroller/processor 240. Base station 110 may include communicationunit 244 and communicate to network controller 130 via communicationunit 244. Network controller 130 may include communication unit 294,controller/processor 290, and memory 292.

Controller/processor 240 of base station 110, controller/processor 280of UE 120, and/or any other component(s) of FIG. 2 may perform one ormore techniques associated with dynamic configuration of power parametervalues, as described in more detail elsewhere herein. For example,controller/processor 240 of base station 110, controller/processor 280of UE 120, and/or any other component(s) of FIG. 2 may perform or directoperations of, for example, method 500 of FIG. 5, method 600 of FIG. 6,and/or other processes as described herein. Memories 242 and 282 maystore data and program codes for BS 110 and UE 120, respectively. Ascheduler 246 may schedule UEs for data transmission on the downlinkand/or uplink.

As indicated above, FIG. 2 is provided merely as an example. Otherexamples may differ from what is described with regard to FIG. 2.

Battery life is an important consideration for UEs 120, especially forUEs 120 that operate in remote areas that may not be easily accessibleto replace a battery, such as an NB-IoT UEs and/or the like. However,throughput is also an important consideration for UEs 120, and oftendirectly conflicts with power savings and battery life since more poweris required for high throughput as compared to low throughput. In somecases, a UE 120 may use a discontinuous reception (DRX) cycle totransition between a sleep state and an active state to conserve batterypower when there is no data for the UE 120 to transmit or receive.However, a UE 120 may benefit from additional power saving in additionto a DRX cycle or as an alternative to a DRX cycle.

Some techniques and apparatuses described herein permit a UE 120 totransition among different power configurations, which are defined bydifferent values for different operation power parameters (e.g.,transmission power parameters and/or reception power parameters), thatimpact the amount of power consumed by the UE 120 (e.g., to communicatewith a base station 110 or to perform other operations). An operationpower of UE 120 may include a transmit power or a receive power, whichmay be affected by an operation power parameter, such as a transmitpower parameter or a receive power parameter. Based at least in part onenabling UE 120 to transition among different power configurationsassociated with different values for different operation powerparameters, UE 120 may optimize an operation power of UE 120 (e.g., UE120 may optimize a transmit power for transmissions to BS 110 or areceive power for reception of signaling from BS 110).

In some aspects, these transitions may be signaled by a base station 110based at least in part on traffic volume for the UE 120, which mayassist with improving throughput (e.g., when data is available for theUE 120), and which may assist with extending battery life of the UE 120(e.g., when data is not available for the UE 120). Furthermore, thesetransitions may be signaled dynamically, such as in downlink controlinformation (DCI) and/or a media access control (MAC) control element(CE) (MAC-CE), which may conserve battery power as compared toreconfiguring the UE 120 using a radio resource control (RRC) message,and which may allow the UE 120 to be reconfigured quickly as conditionsassociated with the UE 120 change. Furthermore, some techniques andapparatuses described herein are capable of indicating powerconfigurations using a small amount of overhead, thereby conservingnetwork resources.

FIG. 3 is a diagram illustrating an example 300 of dynamic configurationof power parameter values.

At 305, a UE 120 may receive, from a base station 110, a firstindication of a set of operation power parameters and a secondindication of a set of values associated with the set of operation powerparameters. The set of values for the set of operation power parametermay define a power configuration (e.g., for transmission and/or forreception) for the UE 120. As is described in more detail below, in someaspects, the first indication and the second indication may be includedin DCI (e.g., UE-specific DCI, group-common DCI, cell-specific DCI,and/or the like), a MAC-CE, or a combination of the DCI and the MAC-CE.The set of operation power parameters may be selected from a pluralityof sets of operation power parameters that are configurable (e.g., arecapable of having different values) to achieve different powerconfigurations for the UE 120. In other words, a first powerconfiguration may be defined by a first subset of possible operationpower parameters configured with a first set of values and a secondpower configuration may be defined by a second subset of possibleoperation power parameters configured with a second set of values. Inthis case, at least one operation power parameter or at least one valuemay differ between the first subset of possible operation powerparameters and the second subset of possible operation power parametersor the first set of values and the second set of values, respectively,to define different power configurations.

The set of values may include a value for each operation power parameterincluded in the set of operation power parameters. In some aspects, theset of values may define a power configuration for the UE 120, and/ordifferent sets of values may correspond to different powerconfigurations for the UE 120. Thus, the UE 120 may be capable ofoperating using different power configurations, which may consume adifferent amount of power for communications of the UE 120, may causethe UE 120 to operate with different power consumption rates, and/or thelike.

In some aspects, the base station 110 may determine the set of operationpower parameters and/or may select the set of operation powerparameters, from the plurality of sets of operation power parameters,based at least in part on a capability of the UE 120, which may besignaled to the base station 110 in a UE capability report, may dependon a device type of the UE 120 signaled to the base station 110 (e.g., aUE class, a UE category, and/or the like), and/or the like. For example,the UE capability report may indicate one or more operation powerparameters that can be configured or reconfigured for the UE 120, andthe base station 110 may select a set of operation power parameters tobe configured for the UE 120 based at least in part on such acapability. In this case, as an example, the UE capability report mayindicate that UE 120 is capable of having a bandwidth part for UE 120configured to a particular bandwidth part (e.g., the particularbandwidth part may be a value for a bandwidth part configurationparameter) and/or that a delay between a DCI and an uplink associatedtherewith is configurable to a particular quantity of slots or symbols(e.g., the particular quantity may be a value for a DCI to uplinktransmission delay configuration parameter). In this way, the basestation 110 may ensure that the UE 120 is capable of reconfiguringoperation power parameters indicated by the base station 110, therebyreducing errors, improving battery life and/or throughput (e.g.,according to the configuration), and/or the like.

Additionally, or alternatively, the base station 110 may determine theset of values and/or may select the set of values, from a plurality ofsets of values, based at least in part on a capability of the UE 120, adevice type of the UE 120, and/or the like, in a similar manner asdescribed above. For example, a UE capability report may indicate, forone or more operation power parameters, values with which the UE 120 iscapable of configuring an operation power parameter. Returning to theprevious example, the UE capability report may identify a bandwidth partthat is to be configured for UE 120, a value for the quantity of slotsor symbols, and/or the like. The base station 110 may select a set ofvalues with which to configure the set of operation power parametersbased at least in part on such a capability. In this way, the basestation 110 may ensure that the UE 120 is capable of reconfiguringoperation power parameters indicated by the base station 110, therebyreducing errors, improving battery life and/or throughput (e.g.,according to the configuration), and/or the like.

Additionally, or alternatively, the base station 110 may determine theset of values based at least in part on whether there is data availablefor the UE 120, based at least in part on a volume of network traffic(e.g., data) associated with the UE 120, and/or the like. For example,if there is data available for the UE 120 or if the amount of networktraffic associated with the UE 120 satisfies a threshold, then the basestation 110 may configure the UE 120 with a set of values for a set ofoperation power parameters that results in a high throughput (e.g., andhigh power consumption) power configuration for the UE 120. For example,the base station 110 may configure the UE 120 with a wide bandwidth partthat is larger than a threshold, a short downlink control channelmonitoring periodicity that is smaller than a threshold, a large numberof MIMO layers that is larger than a threshold, a short hybrid automaticrepeat request (HARQ) timeline that is larger than a threshold, and/orthe like. Conversely, if there is no data available for the UE 120 or ifthe amount of network traffic associated with the UE 120 does notsatisfy a threshold, then the base station 110 may configure the UE 120with a set of values for a set of operation power parameters thatresults in a low power consumption (e.g., and low throughput) powerconfiguration for the UE 120. For example, the base station 110 mayconfigure the UE 120 with a narrow bandwidth part, a long downlinkcontrol channel monitoring periodicity, a small number of MIMO layers, along hybrid automatic repeat request (HARQ) timeline, and/or the like.

In some aspects, the plurality of sets of operation power parametersand/or the plurality of sets of values may be predetermined (e.g.,specified according to a wireless communication standard). Additionally,or alternatively, the plurality of sets of operation power parametersand/or the plurality of sets of values may be indicated to the UE 120 bythe base station 110 in a signaling message, such as an RRC message(e.g., an RRC configuration message, an RRC reconfiguration message,and/or the like) and/or another signaling message.

At 310, in some aspects, the first indication and the second indicationmay be transmitted and/or received in DCI. For example, a first field ofthe DCI (shown as “Parameter(s)”) may indicate the set of operationpower parameters, and a second field of the DCI (shown as “Value(s)”)may indicate the set of values to be configured for the set of operationpower parameters. In example 300, the set of operation power parametersis indicated using an index, for the first indication, with an indexvalue of zero (shown as “Parameter subset index=0”).

Although some aspects are described herein as using an index value forthe first indication, other types of indicators may be used for thefirst indication. Additionally, or alternatively, the first DCI fieldmay explicitly identify a single operation power parameter (e.g., ratherthan an index that points to a set of operation power parameters), andthe second DCI field may indicate a value for the single operation powerparameters. In some aspects, multiple instances of the first DCI fieldand the second DCI field may be used to indicate multiple operationpower parameters and values corresponding to those operation powerparameters. Furthermore, although the index values are shown as beingexpressed using a number (e.g., an integer), the index values may beexpressed using an enumeration, in some aspects. As further shown, theset of values may be included in the DCI (e.g., may be explicitlyindicated in the second field of the DCI). Alternatively, the secondfield of DCI may include an index (referred to herein as a value vectorindex) to indicate the set of values, as described below.

At 315, the index value may correspond to and/or identify the set ofoperation power parameters. For example, a first index value (shown as“0”) may correspond to a first set of operation power parameters (shownas two operation power parameters: “{minimum k0, periodic CSI}”), asecond index value (shown as “1”) may correspond to a second set ofoperation power parameters (shown as three operation power parameters:“{PDCCH AL, number of PDCCH candidates, Scell PDCCH monitoring}”), andso on. In some aspects, a set of operation power parameters may includea single operation power parameter. In some aspects, a set of operationpower parameters may include multiple operation power parameters (e.g.,a list of operation power parameters). Although example 300 shows anindex value in the first field of the DCI, in some aspects, the firstfield of the DCI may list the set of operation power parameters (e.g.,the set of operation power parameters may be explicitly indicated in theDCI, rather than identified using an index value). In some aspects, theDCI may be a particular type of DCI. For example, when the firstindication and the second indication are outside of an active time ofthe UE, the first indication and the second indication may be a PDCCHwake up signal DCI. Additionally, or alternatively, the DCI may be a DCItype 0-1, a DCI type 1-1, and/or the like.

In some aspects, relationships between index values and correspondingsets of operation power parameters (e.g., a one to one relationshipbetween a single index value and a single set of one or more operationpower parameters) may be predetermined (e.g., specified according to awireless communication standard). Additionally, or alternatively, one ormore relationships between index value(s) and set(s) of operation powerparameters may be indicated to the UE 120 by the base station 110 in asignaling message, such as an RRC message and/or the like. In this way,the UE 120 and the base station 110 may use an index value or a similarindicator to identify a set of operation power parameters, therebyconserving signaling overhead (e.g., in DCI, a MAC-CE, and/or the like).

At 320, in some aspects, the second indication may include a valuevector index that indicates the set of values. In example 300, the setof values is indicated using a value vector index with an index value of1 (shown as “Value vector index=1”). Although some aspects are describedherein as using an index value for the second indication, other types ofindicators may be used for the second indication.

At 325, the value vector index may correspond to and/or identify the setof values. For example, a first value vector index value (shown as “0”)may correspond to a first set of values (shown as two values: “{0,“enabled”}”), a second value vector index value (shown as “1”) maycorrespond to a second set of values (shown as two values: “{2,“disabled”}”), and so on. In some aspects, a set of values may include asingle value (e.g., when the set of operation power parameters includesa single operation power parameter. In some aspects, a set of values mayinclude multiple values (e.g., when the set of operation powerparameters includes multiple operation power parameters). In someaspects, the number of values included in the set of values may be thesame as the number of operation power parameters included in the set ofoperation power parameters to which the set of values corresponds.

In some aspects, relationships between vector indices and correspondingsets of values (e.g., a one to one relationship between a single indexvalue and a single set of one or more values) may be predetermined(e.g., specified according to a wireless communication standard).Additionally, or alternatively, one or more relationships between vectorindex value(s) and set(s) of values may be indicated to the UE 120 bythe base station 110 in a signaling message, such as an RRC messageand/or the like. In this way, the UE 120 and the base station 110 mayuse a vector index value or a similar indicator to identify a set ofvalues, thereby conserving signaling overhead (e.g., in DCI, a MAC-CE,and/or the like).

At 330, the UE 120 may configure itself to operate using a powerconfiguration indicated by the set of values, indicated by the secondindication, for the set of operation power parameters indicated by thefirst indication. For example, the UE 120 may configure the set ofoperation power parameters using the set of values. Additionally, oralternatively, the base station 110 may configure communications withthe UE 120 based at least in part on the power configuration (e.g., theset of values for the set of operation power parameters). The UE 120 andthe base station 110 may communicate based at least in part on the powerconfiguration.

In some aspects, if the UE 120 is not capable of configuring anindicated operation power parameter with a value indicated for theoperation power parameters, then the UE 120 may ignore such indicationsand may continue to operate using a value, for the operation powerparameter, with which the UE 120 is already operating. Alternatively,the UE 120 may configure the indicated operation power parameter with avalue that the UE 120 is capable of using and that is closest to anindicated value. In some aspects, the set of values indicated to the UE120 may include a null value for one or more operation power parameters.For example, the base station 110 may transmit a null value for anoperation power parameter based at least in part on a determination thatthe UE 120 is not capable of configuring the operation power parameter(e.g., according to a UE capability report and/or the like, as describedabove). In this case, the UE 120 may continue to operate using a value,for the operation power parameter, with which the UE 120 is alreadyoperating. In this way, errors may be reduced while still permittingconfiguration of other operation power parameters to improve batterylife, improve throughput, and/or the like.

In some aspects, different sets of operation power parameters mayinclude different combinations of operation power parameters from aglobal set of operation power parameters that includes all possibleoperation power parameters capable of being reconfigured for a powerconfiguration. In this case, a message that includes all operation powerparameters for communication may be a bandwidth part switch message. Insome aspects, all of the sets of operation power parameters, other thanthe global set of operation power parameters, are mutually exclusive. Inthis case, a specific operation power parameter is only included in asingle set of operation power parameters. Alternatively, an operationpower parameter may be included in multiple sets of operation powerparameters. In some aspects, the set of operation power parametersindicated to the UE 120 may be the global set of operation powerparameters that includes all operation power parameters included in allother sets of operation power parameters of the plurality of sets ofoperation power parameters.

In some aspects, the set of operation power parameters may include oneor more frequency domain configuration operation power parameters, suchas an operation power parameter relating to a reference signal forbandwidth part (BWP) switching (e.g., whether to enable or disable UEmonitoring and/or processing of the reference signal), an operationpower parameter relating to a BWP configuration (e.g., a BWP index for aBWP via which the UE 120 is to communicate and/or monitor for a wakeupsignal, whether to switch to a default BWP upon wakeup, whether toremain on an active BWP at wakeup, and/or the like), an operation powerparameter relating to secondary cell (SCell) activation (e.g., whetherSCells are enabled or disabled), an operation power parameter indicatingwhether to monitor and/or decode a physical downlink control channel(PDCCH) of an SCell (e.g., shown as “Scell PDCCH monitoring” in FIG. 3),an operation power parameter indicating whether SCells useself-scheduling or cross-carrier scheduling, an operation powerparameter indicating whether search spaces are shared across cells(e.g., serving cells), an operation power parameter indicating one ormore SCells to which one or more of the above frequency domainconfiguration operation power parameters are to be applied, and/or thelike.

Additionally, or alternatively, the set of operation power parametersmay include one or more time domain configuration operation powerparameters, such as an operation power parameter indicating a time delay(e.g., in slots, symbols, and/or the like) between DCI (e.g., on thePDCCH) and a corresponding data or reference signal transmission (e.g.,where the UE 120 can configure a low power configuration during the timedelay), an operation power parameter indicating a time domain resourceallocation (TDRA) table to be used by the UE 120, and/or the like.

Additionally, or alternatively, the set of operation power parametersmay include one or more scheduling configuration operation powerparameters, such as an operation power parameter indicating whether touse slot-based or non-slot-based scheduling, an operation powerparameter indicating whether multi-slot scheduling is enabled ordisabled (e.g., multi-slot scheduling with a single DCI scheduling dataor a reference signal in multiple slots), and/or the like.

Additionally, or alternatively, the set of operation power parametersmay include one or more multiple input multiple output (MIMO)configuration operation power parameters, such as an operation powerparameter indicating a number of antennas, panels, and/or beams to beused by the UE 120 and/or the base station 110, an operation powerparameter indicating a number of MIMO layers to be used by the UE 120(e.g., for transmission, for reception, and/or the like), an operationpower parameter indicating a maximum number of antennas, panels, beams,layers, and/or rank values to be used by the UE 120, an operation powerparameter indicating whether the UE 120 is to process or reportmeasurements of channel state information reference signals (CSI-RS)regardless of whether periodic CSI-RS are configured for the UE 120(e.g., shown as “Periodic CSI” in FIG. 3), and/or the like.

Additionally, or alternatively, the set of operation power parametersmay include one or more discontinuous reception (DRX) configurationoperation power parameters, such as one or more DRX timer values to beused by the UE 120 (e.g., an on-duration timer, an inactivity timer, ashort cycle timer, and/or the like), an indication of whether a DRXshort cycle is enabled or disabled, and/or the like.

Additionally, or alternatively, the set of operation power parametersmay include one or more processing timeline configuration operationpower parameters, such as an operation power parameter indicating aminimum timing offset to be used by the UE 120 for one or more k values(e.g., a k0 value indicating a timing between a downlink grant andcorresponding downlink data transmission, a k1 value indicating a timingbetween a downlink data transmission and corresponding acknowledgement(ACK) or negative acknowledgement (NACK) feedback, a k2 value indicatinga timing between an uplink grant and a corresponding uplink datatransmission, a k3 value indicating a timing between ACK or NACKfeedback and a corresponding downlink data retransmission, and/or thelike), an operation power parameter indicating a minimum timing offsetto be used for CSI (e.g., a timing between DCI and aperiodic CSI-RS),and/or the like. For example, an operation power parameter indicating aminimum k0 value (shown as “minimum k0”) is shown in FIG. 3.

Additionally, or alternatively, the set of operation power parametersmay include one or more downlink control channel (e.g., PDCCH)configuration operation power parameters, such as an operation powerparameter indicating a periodicity of monitoring occasions, an operationpower parameter indicating one or more downlink control channelcandidate aggregation levels to be monitored by the UE 120 (e.g., shownas “PDCCH AL” in FIG. 3), an operation power parameter indicating anumber of downlink control channel candidates to be monitored for one ormore configured aggregation levels (e.g., shown as “number of PDCCHcandidates” in FIG. 3), an operation power parameter indicating one ormore control resource sets (CORESETs) to be monitored by the UE 120, anoperation power parameter indicating one or more search space sets to bemonitored by the UE 120, an operation power parameter indicating one ormore DCI formats to be monitored by the UE 120, an operation powerparameter indicating one or more cells to which one or more of the abovedownlink control channel configuration operation power parameters are tobe applied, and/or the like.

Additionally, or alternatively, the set of operation power parametersmay include one or more wakeup signal configuration operation powerparameters, such as an operation power parameter indicating whether theUE 120 is to monitor for and/or process wakeup signals, and/or the like.

Additionally, or alternatively, the set of operation power parametersmay include one or more radio resource management (RRM) configurationoperation power parameters, such as an operation power parameterindicating a configuration for RRM, an operation power parameterindicating a periodicity of measurement occasions, an operation powerparameter indicating one or more cells to which one or more of the aboveRRM configuration operation power parameters are to be applied, and/orthe like.

By dynamically signaling a set of operation power parameters (e.g.,power operation power parameters) and a corresponding set of values forthose operation power parameters, the base station 110 may activatedifferent power configurations for the UE 120, which may assist withquickly reconfiguring the UE 120 as conditions associated with the UE120 change. For example, the UE 120 may be reconfigured to a highthroughput power configuration to improve throughput when a large amountof data is available for the UE 120 (e.g., a threshold amount of data),and may be reconfigured to a low power consumption setting to extendbattery life of the UE 120 when a small amount of data or no data isavailable for the UE 120. Furthermore, signaling different powerconfigurations using DCI (and/or a MAC-CE, as described below inconnection with FIG. 4) may conserve battery power of the UE 120 and/ormay conserve network resources as compared to reconfiguring the UE 120using an RRC message (e.g., which may be a larger message than DCIand/or a MAC-CE).

As indicated above, FIG. 3 is provided as an example. Other examples maydiffer from what is described with respect to FIG. 3.

FIG. 4 is a diagram illustrating an example 400 of dynamic configurationof power operation power parameter values. FIG. 4 shows an example ofusing a MAC-CE in addition to or as an alternative to using DCI toconfigure a power configuration for the UE 120, as described above inconnection with FIG. 3.

At 405, in some aspects, the set of operation power parameters (shown as“Power related operation power parameter(s)”) and the set of values(shown as “Value(s)”) corresponding to the set of operation powerparameters may be indicated in a MAC-CE. The set of operation powerparameters may be indicated using a first indication in the MAC-CE, andthe set of values may be indicated using a second indication in theMAC-CE. Additional details are described above in connection with FIG.3. For example, any of the techniques described above in connection withindicating the set of operation power parameters and/or the set ofvalues in DCI can be applied when indicating the set of operation powerparameters and/or the set of values in the MAC-CE. This may reduce DCIand/or MAC-CE overhead and may simplify UE processing, which mayconserve battery power of the UE 120.

At 410, in some aspects, the first indication of the set of operationpower parameters may be included in a MAC-CE, and the second indicationof the set of values corresponding to the set of operation powerparameters may be indicated in DCI. This may reduce DCI overhead andprovide the ability for flexible, quick reconfiguration of operationpower parameter values.

As indicated above, FIG. 4 is provided as an example. Other examples maydiffer from what is described with respect to FIG. 4.

FIG. 5 is a flow chart of a method 500 of wireless communication. Themethod may be performed by a UE (e.g., the UE 120, the apparatus702/702′, and/or the like).

At 510, the UE may receive a first indication of a set of operationpower parameters. For example, the UE (e.g., using antenna 252, DEMOD254, MIMO detector 256, receive processor 258, controller/processor 280,and/or the like) may receive a first indication of a set of operationpower parameters from a plurality of sets of operation power parametersand a second indication of a set of values for the set of operationpower parameters, as described above. For example, the UE may receiveinformation indicating that the UE is to configure some subset ofpossible operation power parameters and may receive informationindicating that the UE is to configure that some subset of possibleoperation power parameters with some set of values. In some aspects, theUE may receive the first indication and/or the second indication in atleast one of DCI or a MAC-CE.

In a first aspect, the set of operation power parameters includes a listof operation power parameters. In a second aspect, alone or incombination with the first aspect, the set of values is included in atleast one of downlink control information (DCI) or a media accesscontrol (MAC) control element (CE) (MAC-CE). In a third aspect, alone orin combination with one or more of the first and second aspects, the setof values is indicated using a value vector index included in the DCI orthe MAC-CE, wherein the value vector index corresponds to the set ofvalues.

In a tenth aspect, alone or in combination with one or more ofthe first through ninth aspects, the first indication and the secondindication are received in a medium access control (MAC) control element(CE) (MAC-CE). In an eleventh aspect, alone or in combination with oneor more of the first through tenth aspects, the first indication isreceived in a medium access control (MAC) control element (CE) (MAC-CE)and the second indication is received in a downlink control information.

In athirteenth aspect, alone or in combination with one or more of the firstthrough twelfth aspects, the set of parameters includes a parameter thatindicates whether the UE is to process or report measurements of channelstate information reference signals (CSI-RS) regardless of whetherperiodic CSI-RS are configured for the UE.

At 520, the UE may configure the UE to operate using a powerconfiguration based at least in part on a set of values for the set ofoperation power parameters. For example, the UE (e.g., using antenna252, MOD/DEMOD 254, MIMO detector 256, receive processor 258, transmitprocessor 264, TX MIMO processor 266, controller/processor 280, and/orthe like) may configure the UE to operate using a power configuration,of a plurality of power configurations, based at least in part on theset of values for the set of operation power parameters, as describedabove.

At 530, in some aspects, the UE may communicate with a base stationbased at least in part on the power configuration.

In asixteenth aspect, alone or in combination with one or more of the firstthrough fifteenth aspects, the UE may communicate with the base stationusing a low power consumption setting. In some aspects, the UE maycommunicate with the base station using a high throughput setting.

Method 500 may include additional aspects, such as any single aspect orany combination of aspects described in connection with one or moreother processes described elsewhere herein.

Although FIG. 5 shows example blocks of a method 500 of wirelesscommunication, in some aspects, the method 500 may include additionalblocks, fewer blocks, different blocks, or differently arranged blocksthan those shown in FIG. 5. Additionally, or alternatively, two or moreblocks shown in FIG. 5 may be performed in parallel.

FIG. 6 is a flow chart of a method 600 of wireless communication. Themethod may be performed by a base station (e.g., the base station 110,the apparatus 902/902′, and/or the like).

At 610, in some aspects, the base station may determine a set of valuesfor a set of operation power parameters. For example, the base station(e.g., using controller/processor 240 and/or the like) may determine aset of values for a set of operation power parameters, which may,collectively, define a power configuration for a UE, as described above.In a first aspect, the set of values may be for a set of operation powerparameters that are configurable to achieve the power configuration. Ina second aspect, alone or in combination with the first aspect, at leastone of the set of parameters or the set of values are determined basedat least in part on a UE capability, a device type of the UE, adetermination of whether there is data available for the UE, adetermination of a volume of network traffic associated with the UE, ora combination thereof.

At 620, the base station may transmit a first indication of the set ofoperation power parameters and a second indication of the set of values.For example, the base station (e.g., using controller/processor 240,transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234,and/or the like) may transmit a first indication of a set of operationpower parameters from a plurality of sets of operation power parametersand a second indication of a set of values for the set of operationpower parameters, as described above. In a third aspect, alone or incombination with one or more of the first and second aspects, the firstindication and/or the second indication may be transmitted in at leastone of DCI or a MAC-CE. In a fourth aspect, alone or in combination withone or more of the first through third aspects, different sets of valuescorrespond to different power configurations of the UE.

In a fifth aspect, alone or in combination with one or more of the firstthrough fourth aspects, the first indication is one of a plurality ofindications corresponding to the plurality of sets of operation powerparameters, and wherein a relationship between the plurality ofindications and the plurality of sets of operation power parameters ispredetermined or transmitted by the base station in a radio resourcecontrol (RRC) message. In a sixth aspect, alone or in combination withone or more of the first through fifth aspects, the set of operationpower parameters includes a list of operation power parameters. In aseventh aspect, alone or in combination with one or more of the firstthrough sixth aspects, the set of values is included in at least one ofdownlink control information (DCI) or a media access control (MAC)control element (CE) (MAC-CE). In an eighth aspect, alone or incombination with one or more of the first through seventh aspects, theset of values is indicated using a value vector index included in theDCI or the MAC-CE, wherein the value vector index corresponds to the setof values.

In a ninth aspect, alone or in combination with one or more of the firstthrough eighth aspects, the value vector index is one of a plurality ofvalue vector indexes, and wherein each value vector index, of theplurality of value vector indexes, corresponds to a different set ofvalues of a plurality of sets of values. In a tenth aspect, alone or incombination with one or more of the first through ninth aspects, arelationship between the plurality of value vector indexes and theplurality of sets of values is predetermined or transmitted by the basestation in a radio resource control (RRC) message. In an eleventhaspect, alone or in combination with one or more of the first throughtenth aspects, one set of operation power parameters, of the pluralityof sets of operation power parameters, includes all operation powerparameters included in all other sets of operation power parameters ofthe plurality of sets of operation power parameters. In a thirteenthaspect, alone or in combination with one or more of the first throughtwelfth aspects, the first indication and the second indication aretransmitted in a downlink control information (DCI).

At 630, the base station may communicate with the UE based at least inpart on the set of values for the set of operation power parameters. Forexample, the base station (e.g., using transmit processor 220, TX MIMOprocessor 230, MOD/DEMOD 232, antenna 234, MIMO detector 236, receiveprocessor 238, controller/processor 240, and/or the like) maycommunicate with the UE in accordance with a power configuration, of aplurality of power configurations, configured based at least in part onthe set of values for the set of operation power parameters, asdescribed above.
